Are plants passive green things, just waiting for the next passing mouth to munch on them? Or do they sometimes fight back? This week's programme is devoted to the botanical poisoners, the tricksters and the carnivores that turn the tables and seek revenge on the animal kingdom. Featuring Amy Stewart, author of Wicked Plants – The A-Z of Plants That Kill, Maim, Intoxicate and Otherwise Offend; RHS Editor and flytrap fan Gareth Richards; and Dr Chris Thorogood, Deputy Director of Oxford Botanic Garden.
